FISH-SCALING MACHINE.

Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed December 5, 1908. Serial No. 486,052.

o all whom it may concern:

zen of the United States, residing at Chicago,-

in the county of Cook and State of Illinois, have invented new anduseful Improvements in Fish-Scaling Machines, of which the following isa specification, reference being had to the drawings forming a partthereof.

The purpose of this invention is to provide an improved apparatus forremoving scales from fish.

It consists of the elements and features of construction shown anddescribed as indicated in the claims.

In the drawings :Figure l is a partly sectional side elevation of amachine embodying this invention, the section being made axially throughone of the rolls and its operating gears. Fig. 2 is an end elevation ofthe same. Fig. 3 is a section at the line 33 on Fig. 2.

The machine shown in the drawings comprises a rigid frame which consistsof two side members, each formed of two angleiron uprights connected bylongitudinal angle bars, 2, These two side members are rigidly joined atthree places,-(1) at their lower part by the journaled bearing bars, 3,3, of the main power shaft, 4, which are bolted to the uprights; (2). bythe carrying bracket, 10, hereinafter mentioned, which is mounted on thelower longitudinal angle bars, 2, and, (3) at the upper part by thecross tie, 5, which is bolted to and connects the upper longitudinalangle bars, 2, 2. The power shaft, 4, is provided with a fly wheel, (3,designed and adapted to be operated by hand for rotating the shaft. Onsaid power shaft there are mounted for slid1ng,preferably by the splinedconnection illustrated, hearing brackets, 7, 7, in which there arejournaled secondary shafts, 8, 8, at right angles to the-power shaft, 4,operatively connected with said power shaft for rotation by theintermeshing bevel gears, 4 and 8 0n said power shaft and secondaryshafts respectively, the gears, 4*, being feathered on the shaft, 4, forrotation therewith and slidingthereon, as indicated, by the pins, 4*,taking through the slots, 4, in the shaft. Upper journal bearings forthe shafts, 8, 8, are providedin journal boxes, 9, mounted for slidingbetween the upper longitudinal frame bars, 2, 2, of the two sidemembers, respectively. The shafts, 8, 8, carry scale-detaching rolls,11, 11, and the gear connections described are arranged to revolve saidrolls in the same direction at their proximate sides. For the purpose ofdetaching the scales, these rolls may be covered with wire card, 11, asillustrated. For propelling or drawing the fish to be scaled between therolls there is provided a feeding device comprising a screw shaft, 12,journaled in the bracket, 10, mounted as described upon the two lowerlongitudinal angle bars, 2, 2, extending across the same. On the innerend of said screw shaft, 12, there is secured a bevel gear, 13, whichmeshes with and is driven by a bevel gear, 14, fast on the shaft, 4.

15 is a traveler threaded for engaging the shaft, 12, and havingconnected to it for movement therewith a carriage consisting of a bar,16, mounted for sliding in a hearing, 10*, on the gearing bracket, 10,and having rigid with it two upright arms, 1G and 16*, respectively,which extend substantially parallel to the shafts, 8, 8, at oppositesides of the common plane of the axes of said shafts, and at oppositesides of the two rolls. Each of said uprights, 16 and 16", carries afish-engaging hook, 17, the hook being connected with one of theuprights by means of a tensile spring, 18, the two hooks being adaptedand designed to engage the two ends of the fish body, as shown in Fig.2.

It will be understood from the foregoing description that the rotationof the power shaft, 4, not only rotates the two rolls, 11, 11, so thatthey may operate'by their properly armored surfaces for detaching thescales from the fish passed between them, but also by rotation of theshaft, 12, causes the fish carriage having the traveler for engaging thescrew shaft to be propelled transversely to the plane of the axes of thetwo rolls so as to draw the fish through between the latter. It isdesigned thatthe fish shall be entered and advanced tail foremostbetween the rolls, being thus entered at the side of the meeting planeof the rolls toward which they revolve at their proximate sides, so thatthe direction of rotation of the rolls on the surface of the fish willbe the opposite ready disengagement from the screw shaft,

being for that purpose made in two parts hinged together as shown, thelower part, 15, being latched to the other part for operativeengagement. When the fish has been propelled through between the rollsas described the operator, unlatching the lower member, 15, of thetraveler, may spring up the bar, 16, at the end to which the traveler issecured, disengaging the latter from the screw shaft,'so that the fishcarriage, comprising said traveler and bar and uprights, can beimmediately thrown back to the starting point for repetition of theaction. For holding the two rolls toward each other so that they maypress effectively upon the body of the fish, andmay nevertheless beadapted to spread to permit fish of different sizes .to pass throughbetween them, there are provided springs, l9, l9, connecting the twosliding gearing brackets, 7, 7.

For some purposes it may be desirable to provide for equalizing thespreading move-- ment of the two scale-detaching rolls so that they maybe moved to equal extent from their meeting plane by any action tendingto spread them. For this purpose the two gearing brackets, 7, 7, andalso the two journal bearings, 9, 9, are connected by lazytongsstructures, 20, 20, on which the middle pivot, 21, is fixedly mounted,that of the lower lazy-tongs being mounted in alug, 22 of a longitudinalbar, 22, extended between the two uprights, 1, l, at one side, and thepivot of the upper lazy-tongs being mounted in the cross-tie, 5. Toprevent cramping of the bearings of the shafts, 8, 8, in spreading ofthe rolls, and to accomplish this without unduly extending the slidebearing of the gearing bracket, 7, on the shaft, 4, there ispreferably'provided a vertical rock-shaft, 23, having journal hearingson one of the uprights, 1, said shaft having two lever arms, 23, nearits upper and lower ends respectively, conneccted respectively by links,23", with the gearing bracket, 7, and journal bearings, 9, of one of theroll shafts. This expedient, together with the lazy tongs constructiontransmitting equal movement from the bearings of one shaft to thecorresponding bearings of the other shaft, relieves both of said shaftsof liability tocrampin I claim 1. In a fish-scaling machinv'i'z, incombination with a pair of scale- 'etaching rolls; means for revolvingthemin the same direction at their proximate sides; a screw shaftextending transversely to the common plane of the axes of said rolls;means for rotating 1t; a traveler engaged by the screw shaft, and meansfor guiding it for travel therealong, such traveler having two armsrespectively at opposite sides of said plane and of the rolls, andfish-engaging means on each of said arms.
